Why a Four-Balloon Diamond Design?
Benefits:Advantageous payloadStability in all directionsVectored Thrust

Control Systems
Vectored Thrust: one servo controls pitch of motors, another servo controls yaw of motorsRC control (human factors)

Aerodynamic Analysis
Maximum Thrust (from table):1.4N total from 2 large motors
Mass: 1.2-1.4kgMaximum Acceleration = Thrust/Mass = .9-1m/s2
Terminal Velocity = 1-1.2 m/sTime Estimate: 90-130 seconds

Design Evolution
Reshaping control assembly to allow roomfor propellers to turn
Motors mounted under control assembly instead of on topExtra bracing required on control assemblyPsychological evolution: new improved team name!
<-- motor mount prototype

Conclusions
Designed for stability and payload rather than aerodynamics/speedBuilding left: attach motor mount to fuselage, balloon attachment netTesting: controls response, practice using rc controller
